HINGED OVE BURNER.

Application. filed .Tilly 2'?, 1923. Serial E333. SHL'S,

ments in Hinged @ven Burners. of which the following is :ispeciiezition.

My invention relates to iinprorements in electriooii'en burners andConsists essentially of a plnraiity of spaced. parallel rails or guides`for fire hars or resistance insulating bars, integral with lateralmetallic straps hinged toltne oven iloor structure and Connected attheir opposite enrls hy a cross meinber which is provided with means forfastening it to the oven structure, an lateral elevated strips on thestudi straps, and (letacliable therefrom, for the purpose o retainingsaifl tire hars from lateral movement.

' The principal object of the invention is to provide a suitablyconstructed heater element of the type carrying space rows ofpluralities of fire hars, or resistance stringing bars 0r blocks heldinposition nv spaced parallel rails or g'iiidee, which may e eesiy andreadiy swung to a sulsstont y perpendieiilar position or e positionintermedi ete O the lat-'tor and its normally horizontal position, forthe purpose ofl clearing; the oven floor beneath.

A further object is to provirle menus in heater element of the FlussSpeeiierl, lo keep the fire liars in girone? relative position unilwhich may he eosily :mil readily fietaolieil so as to permitrepliirement oi' any of said fire bars.

A still further oliiert is to provide suoli a (levier- Whirli `will 'nesimple, (liirohlo, elli cient in operation, an?! inexpensive toinsinufzieture.

These` together w'tli other objects', he attained by the construfztion,combination and arrangement o45 the parts as will he hereinafter morefully rlnsorihnil, illustratori in the ucroinpfinying drawing, undpointed out in the iflaiins hereunto zippenclerl.
